摘　　要：介绍了钨冶炼过程中含砷含氨氮废水的治理工程实例,并从方法与原理、工艺流程及效果、存在的问题与改进等方面作了说明。检测结果表明,采用"石灰-亚铁盐除砷、湿式催化氧化吹脱除氮联合工艺"可实现对APT生产过程中废水的有效治理。Description is made of the practice of As-/NHa/N-containing waste water treatment in W metallurgy in terms of process, principle, process flowsheet, efficiency, existing problems and improvement. The results showed that the waste water from APT production can be effectively controlled with combined process of ＂Lime ferrous salt for As removal;wet-method catalytic oxidation blowing for N removal＂.
